with Disney DVD play the disk with 
<code>
mplayer -v dvdnav:// -dvd-device /dev/sr0 2>&1 | grep TITLE
</code>

without a title number, then select the main feature in the menu and look at 
the debug output, you'll see which title is played, when the message 
"switching to track xy" appears.

dump main feature (1 in this example) to vob file
<code>

===== tricks =====

Inves­ti­gat­ing the device mode pages with sdparm, I came up with the fol­low­ing to make it stop try­ing to read those blocks over and over again: 
<code>
sdparm –set=RRC=0 /dev/sr0
</code>


Repair index and/or merge
<code>
mencoder -forceidx -o output.avi -oac copy -ovc copy input1.avi [input2.avi ...]
